ZERODUR® Window
ZERODUR® Window

  • The ZERODUR® window have a coefficient of thermal expansion (CTE) of ±0.10 x 10-6/°C, which is an order of magnitude lower than most glass types. The low CTE allows these mirrors to have a consistent reflected wavefront, even when exposed to environments with varying temperature or illumination sources with changing intensity. 

  • CRYSMIT offer λ/20 flatness and 20-10 surface quality ZERODUR® window or Mirrors . Multiple metallic and enhanced metallic coating options are available, allowing for these mirrors to be easily integrated into applications in both the visible and infrared spectrum.

  • Technical properties for ZERODUR® glass-ceramic - SCHOTT.

What are the advantage of ZERODUR® Window ?

  • Thermal expansion: ZERODUR® is known for its incredibly low coefficient of thermal expansion. This means it doesn't significantly expand or contract with temperature changes, making it extremely stable and reliable in various environmental conditions.


  • Stability over time: The extremely low expansion properties of ZERODUR® make it very stable over time. This is one reason why it is commonly used in applications that require high precision and stability, such as astronomical telescopes and lithography machines used in semiconductor manufacturing.


  • Excellent Surface Quality: ZERODUR® window can be polished to an excellent surface quality (10/5 scratch/dig, λ/20 flatness), making it ideal for high precision optics.


  • Resistance to environmental conditions: ZERODUR® is highly resistant to many environmental conditions. It has high chemical stability and is resistant to many common chemicals. It is also resistant to scratching and abrasion, and it has high resistance to radiation.


  • Precision: Due to its low thermal expansion, ZERODUR® can be manufactured to extremely high precision, 


  • Lightweight: ZERODUR® can be manufactured in a lightweight version, which is particularly useful for space telescopes applications where weight is a critical factor.
